Application led November. 6, 192:1.

tained by means: ofa double V-shapd spring.

lt has been customary to, cement or glue; the pad toy the metal faces ofthe head, but it has been found by experience thaty owing to the wearupon thel pad, when tl pelisher is in use, the pad frequently )ecomesloosened from the polishing head.

The spring, as shown in the Snyder patent, above referred to, is notpermanently attached to the polisher, but is only fricr tionally engagedthereby when in the operative position, making it possible to mislay orlose the same when the polishing cloth is removed for cleaning orrenewing,

rllhe object of the present improvement is to provide means forattaching the pad firinly to the polishing head in a manner which willprevent the same from becoming,- looscned by wear; and to provide meansfor securing the spring to the head so that the same cannot becomeaccidentally detached therefrom when the polishing cloth is removed.

The above and other objects may be attained by providing channels uponthe inner faces of the head to receive wooden strips to which the endsof the pad are secured by tacks or the like; and to provide bosses uponthe head to receive the loops of the springand retain the same againstaceidental displacement.

An embodiment of the invention thus set forth in general terms, isillustrated in the accompanyingg,` drawing, in which- Figure 1 is a sideelevation of the im proved floor polisher;

g'fig. 3, a seetion on-the line 3-,-3., ligg--A 1;g and,

Fig.l 4f, a detail perspective view of' the spring.

Similar numerals refery tol Similar parts throughout the drawing.v

rihe polishinghead may be of east irerr or the like, and is V-.shaped,.cempris-ingy the two converging side members 1, the. apex 2 thereofbeing, rounded and prefere. ably reinforced, a vertical web 3,ext-ending longitudinally between the side members, terminatingat peintsspaced from the front and rear edges thereof.

A thickened transverse Wall 4. @Oneens with the front edge of the rib3., and ter'- mnates at peints spaced from the @dass of the head, andprovided. anon @eeh eed with the Centrally located bosses 5, termi-rnating just` short of the plane of they side edges of the head.

A rearwardly tapered extension 6 is formed upon the central rib 3, towhich the handle 7 is pivotally connected, as by the ears 8 and pin 9.The rear edge portion o-f each side member is turned inwardly andforwardly, as shown at 10, and a rearwardly disposed curved flange 11 isspaced therefrom, forminlg,v a channel 12 at the rear edge portion ofthe inner face of each side member, a wooden block 13 being,- fixedtherein.

The pad 14 of felt or the like, is located entirely around the outerfaces of the side members 1 and the end portions thereof are securedtothe wooden blocks 13 by means of tacks 15 or the like. In order tosupplement the fastening means of the pad, the same may be cemented tothe outer faces of the side members, if desired.

A polishing cloth 16, of cheesecloth or the like, is placed over thefelt pad and is arranged toI be held at its ends by means of the spring,which comprises two V- shaped side portions 17, having the loops orcoils 18 at their a ices, the outer ends of the arms of the V s beingConnected by the horizontal portions 19.

As illustrated in Fig. 4, this spring is preferably formed of a singlestrand oi Wire shaped as above described, the ends thereof being'connected in any well known manner, such as the sleeve 20.

The loops or coils 18 of the spring are received upon the bosses asshown in Figs. l and 2, thus permanently retaining the spring upon thehead.

The horizontal portions 19 of the spring engage the i'ree end portionsof the polishing cloth adjacent to the inturned ends lO of the sidemembers, pressing the cloth and pad into the angle between the same andthe blocks 13.

lVhen it is desired to remove the cloth in order to clean or replace thesame, the V-portions of the spring may be slightly compressed to permitthe cloth to be withdrawn, the spring remaining in position upon thehead by means of the connection to the bosses 5, whereby when the clothpiece is replaced, it is only necessary to again compress thelf-portions of th spring, in order to place the ends of th cloth beneaththe saine.

rl`he thickened transverse wall il not only provides means forattachment oi" the spring, but also increases the weight of thepolishing head, adding to the ei'iieiency of the same in polishing afloor or the like.

I claim l. A tool of' the character described including a `V'-shapedpolishing head, comprising two converging side members, a wall betweensaid side members, bosses upon said wall, a polishing cloth locatedaround said side members and over the free ends thereof and a springconnected to said bosses, and engaging the end portions of the cloth.

2. A tool of' the character described including a V-shaped polishinghead, comprising two converging side menilficrs, a wall between saidside members, bosses upon Said wall, a polishing cloth located aroundsaid side members and over the iree ends thereoi"l and a spring havingloops connected to said bosses, and engaging the end portions or' thecloth.

3. A tool of the character described in cluding a vtf-shaped polishinghead comprising two converging side members, a wall between said sidemembers, a polishing cloth located around said side members and over thetree ends thereoi and a spring connected to said wall and engaging theend portions of the cloth.

4. A tool of the character described including a 1f-shaped metal head,comprising a pair of converging side members, a channel upon the innerside of each side meinber near the free end thereof, a wooden blockfrictionally held in each channel, and a pad covering said side members,the ends of the pad extending over the free ends ot the side members andconnected to said wooden blocks.

ln testimony that I claim the above, l have hereunto subscribed my name.
